About Us

Welcome to the Wood Windows Sash Balance Company, your direct-to-customer shopping cart for installers and do-it-yourselfers seeking the original and historical ACME DUPLEX and ACME TWIN sash balances. Due to the long lifespan of these balances, many hardware stores receive few replacement orders and often do not carry them. We are here to provide you with the authentic brand you need for your sash window restoration projects.

The History of Sash Balances

The mortise tape balance system replaced most weight and pulley systems in the early 1900s. By the 1920s, the ACME line introduced a single piece of hardware that could replace two mortise balances on each side of a sash. For several decades, millions of sash windows were manufactured using the famous ACME brand, and with the renewed popularity of sash windows today, these balances continue to be essential for all wood windows.

Our Commitment to Quality

At Wood Windows Sash Balance Company, we sell only the authentic, US-made ACME balances you expect. We do not offer foreign-made knock-offs, which may contain inferior internal materials. Our manufacturer provides a lifetime guarantee and stands behind all ACME balances, ensuring you receive the quality and reliability you deserve for your window restoration needs.
